This question was previously asked in
CDS II 2021 General Knowledge Previous Year Paper (14-Nov-2021)
The correct answer is

25%

Given:

Total number of employees in 2019 = 4000

Total number of employees in 2020 = 5000

Calculation: 

For category A, 

Total number employee of category A in 2019 = 20 × 4000/100 = 800

Total number employee of category A in 2020 = 22 × 5000/100 = 1100

For category B,

Total number employee of category B in 2019 = 6 × 4000/100 = 240 

Total number employee of category B in 2020 = 10 × 5000/100 = 500

For category C, 

Total number employee of category C in 2019 = 10 × 4000/100 = 400

Total number employee of category C in 2020 = 11 × 5000/100 = 550

For category D, 

Total number employee of category D in 2019 = 15 × 4000/100 = 600

Total number employee of category D in 2020 = 9 × 5000/100 = 450

For category E, 

Total number employee of category E in 2019 = 27 × 4000/100 = 1080

Total number employee of category E in 2020 = 27 × 5000/100 = 1350

For category F, 

Total number employee of category F in 2019 =  22 × 4000/100 = 880

Total number employee of category F in 2020 = 21 × 5000/100 = 1050

Required Percentage = [(1350 - 1080)/1080] × 100 = 25% 

∴ The correct answer is 25%
